Oh god... One more challenge...
It is hard even now that is August... In Brazil the things are diferent, each world open like 1 month after the other, and sometimes 2 worlds are open in just a week, wich is incredible... Too many players(noobs) failed in other worlds and want a second chance, OR maybe they try to be the TOP 20 of each starting world, LOL.
So, i don't know this system of the US, but i think that it would be at october.
Here is what i think:
Day: October 6th
Time: Around 8:00-14:00
